2000 Years of Disbelief: Famous People with the Courage to Doubt by James A. Haught
“For one heat, all know, doth drive out another,
One passion doth expel another still.”
Monsieur D'Olive, Act V, scene i; reported in Bartlett's Familiar Quotations, 10th ed. (1919).
“Men experience many passions in a lifetime. One passion drives away the one before it.”

"Simone Weil" in The Nation (12 January 1957) http://www.cddc.vt.edu/bps/rexroth/essays/simone-weil.htm
Context: Simone Weil was one of the most remarkable women of the twentieth, or indeed of any other century. I have great sympathy for her, but sympathy is not necessarily congeniality. It would be easier to write of her if I liked what she had to say, which I strongly do not. …I think Simone Weil had both over- and under-equipped herself for the crisis which overwhelmed her — along, we forget, immersed in her tragedy, with all the rest of us. She was almost the perfectly typical passionate, revolutionary, intellectual woman — a frailer, even more highly strung Rosa Luxemburg. … She made up her own revolution out of her vitals, like a spider or silkworm. She could introject all the ill of the world into her own heart, but she could not project herself in sympathy to others. Her letters read like the more distraught signals of John of the Cross in the dark night.
'Where Do We Go From Here?" as published in Where Do We Go from Here : Chaos or Community? (1967), p. 62; many statements in this book, or slight variants of them, were also part of his address Where Do We Go From Here?" which has a section below. A common variant appearing at least as early as 1968 has "Returning violence for violence multiplies violence..." An early version of the speech as published in A Martin Luther King Treasury (1964), p. 173, has : "Returning hate for hate multiplies hate..."
1960s

Context: The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you may murder the hater, but you do not murder hate. In fact, violence merely increases hate. So it goes. … Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.
